To all eo hom t concern.'

Be it known that I, NELSON B. HENRY, a citizen of the United i tates,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Cake-Forming andCage-Loading Mechanism for Oil-Presses, of which the following is aspecification.

My invention has relation to cake forming and cage loading mechanism orapparatus particularly adapted for use in connection with the extractionof veectable oil from the cooked meats of various nuts, seeds andsimilar oil bearing vegetable substances, and it has for its object toprovide an improved mechanism or apparatus of this sort.

My improved mechanism comprises a revolnble mold or die member made withone or more mold cavities or openings, said member being interinittentiyactuated, stepby-step and a presser by which each charge of cooked meatsis compacted and ejected from the molding cavity or opening into a cakereceiving cage or the like, these parts being organized andassocie-,tecL so that the opening or cavity of the molding membertraverses a circular endless path which brings it alternately intocooperative relationship with a cooker and the presser and so that,during one interv l of rest of the revoluble molding member Vthe cavityof the latter is in position to receive a charge of cooked meats from acooker, after which the said member is moved to bring the loaded cavityinto cooperative position with relation to the pre y"er, -'.f'hich is o5erated duringl another perof rest of said member, to compact said chargeand transfer the same, nov: formed iT to a ake, from the ievolublemember to the cage or other receiver.

ln the best form of my invention the revoluble member is made n .th aimilurality of meiding openings or cavities and during' etch period ofrest of sai ity is loaded ivi h a charge om the cooker while the pressoperates upon a previously delivered load or charge within anothercavity.

Another feature of invention in its best form consists in constructingand arranging the parts so that during each period of rest of therevoluble member an ty cavity thereof is stopped during its travel fromthe press toward the cooker in an accessible position to permit of theinsertion therein of certain devices and at the same time a loadedcavity is stopped during its travel from the cooker toward the press inan accessible position to permit of the placing of certain devices ontop of the charge or load. @ther features of my invention arehereinafter pointed out.

in the accompanying drawings:

In the process of extracting vegetable oil from cooked meats of the kindreferred to above a specially constructed container known as a cage issometimes employed, within which a multiplicity of cakes are staclmd.nShe cage when completely loaded with cakes, is placed Within a presswhich i.i piesses the stack of cakes endwise to ex- 1 the oil, aftervhich the case is removed from the press, emptied of its contents,ieiilicd vv'ith sakes, and the operation repeated. My improved mechanismreceives 'the cooked meats freir. the cooker, forms the saine intouniform individual cakes, and stacks the latter within the cage.

ing to the drawings, l is a cooker (indioC ed by dotted lines in Figs. iand 2) of any desired type and having an outlet 2 through which thecontents of said cooker discharge by gravity. Below this outlet 2 is arevoluble molding member 3 herein shown as a disk having four moldingcavities or apertures 4, 1i, 4b and ac. Disk 3 is iournaled at itscenter upon a fixed post 5 and is slidably supported upon a table 6which is supported in an elevated position above a bed plate 7 by thepost 5 and four other posts S anc. 9. 'Upon its under side the disk isiii-ade with four radial slots 41 angularly disposed ninety degreesapart, said slots being open at their outer ends and formed to coperatewith a roll 10 provided upon the top side ci' an internal gear ring 11.rthis gear ring is rotatably supported upon the table (i, whose top bothwithin and outside oit said ring is flush with the top of the latter.

The internal gear ring 11 is driven by a pinion 123 i st on the upperend ot a short vertical shalt 14 journalcd in a bearing on a bracketsecured to the under side of table (i. llt its lower end shaft 14carries a bevel gear 15 driven by a bevel gear 16 fast on a horizontalshaft 1"? `iournaled in bearings on said bracket. This shaft 17 carriesa loose pulley 18 constituting one member of a clutch whose other member18a is splined on said shattso as to be slidable thereon toward and frompulley member 18 to engage and disengage the latter. The pulley 1S iscontinuously driven by means of a belt, not shown.

Immediately above the disk 3 is a bracket 12, supported by the posts 5and 9, which is formed with an aperture 29 through it that is of thesame size and shape at its lower end-as the molding apertures 4, 4a,etc., ot disk 3. At its upper end the aperture 29 communicates throughoutlet 2 with cooker 1 while the lower end thereof occupies a positionimmediately above the path of apertures 4, 4, etc., so as to exactlyregister with each of the latter as it comes into position below saidaperture 29. Above bracket 12 is another bracket 30, triangular in shapeas viewed in plan, which is supported by the posts 5 and 8, said bracket30 having lixed to it a cylinder 31 formed at its lower end with a ramchamber 311 and at its upier end with a ram chamber 312. `Within owerchamber 311 is arranged a relatively arge vertically movable ram 32while a smaller ram 313 movable vertically within upper chamber 312 hasits upper end connect 'l '1y means of a cross head 31.4 and two rods 315with the head ot ram B2. rl`hus the rams 31.2% and are connected so asto move together. @lam 32 is lowered by admitting oil or similar `fluidunder pressure to chamber i311 and simultaneously connecting chamber 312with an outlet or exhaust, while upward movement ot the ram is eiiiectedby admitting fluid under pressure to chamber 312 and simultaneouslyconnecting chamber 311 with the outlet or exhaust. The supply andexhaust of fluid to and from the two chambers 311 and 812 is controlledby valve means which in turn is operated and controlled manually througha hand lever 34 :tulcrumed at 35 upon bracket 30. lVhen swung toward theright, Fig. 1, lever operates the valve means to connect chamber 312with the fluid supply and chamber 311 with the exhaust thus raising ram32, and when swung toward the left said lever operates said valve meansto connect chamber 311 with the fluid supply and chamber 312 with theexhaust thus lowering ram 32. Lever 34 carries a cam roll 36 which ismoved toward and from disk 3 when said lever is swung on its ulcrurn Theroll 3G is yieldingly urged toward disk 3 by a spring 57 one end ofwhich is fastened to bracket 30 and the opposite end to a rod 23pivotally connected at one end to lever 34. At its opposite end rod 23is made with a wedge block 24 oecupying a slot formed in a sleeve 25loosely mounted upon the upper end of a vertical rock shaft 22 journaledin table G (see Figs. 3 and 4). Sleeve 25a occupies a position within ayoke 26, (Figs. 4 and (i) resting upon table 6 and fastened to the rocksha'tt 22. lithin this yoke is also arranged an arm 25 having a roundhole 25b formed therethrough that is occupied by the sleeve 25a, saidsleeve being provided at. its low-er end with an annular outwardlyproject ing 'flange on which arm 25 rests. The arm 25 is free to movevertically within yoke 26 but said arm and yoke are interlocked so thatthey must rotate together. As will be clear` movement of wedge 24 towardthe right, Fig. 4, raises sleeve 252v and arm 25 while movement of saidwedge toward the left, back to the position shown in Fig. 4, permitssaid sleeve. and arm to be lowered, the arm 25 sliding vertically withinthe yoke 26 and sleeve 25a sliding vertically on the upper end of rockshaft 22 during such movements o'f the wedge. lllhen arm 25 is in itslowermost position its free end occupies a position in the path ot roll10 but when lifted by movement ot' wedge 24 toward the right as shown inFig. 4, it is lifted from the path of said roll 10.

Fixed to the lower end of rock shaft 22 is au arm 27 connected by a link28 with one arm, 20, ot a bell-crank lever 19-2O 'tulcrumed at 19FL upona stud projectingy downwardly 'from table G (Figs. 4 and 8). The arm 2()engages the movable clutch member 1S so that when said arm is swungtoward pulley 1S the clutch is set and when swung away from said pulleythe clutch is unset. Vlu the drawings the arm 20 is in position setting'the clutchv and the gear .ring` 1 1 is being driven in. the direction ofthe arrow, Fin. 9. rlhe parts arc so arranged or adjusted that only whenlever 34 is swung to the lull limit of its movement towardnthe right, isarm 25 raised above the path oit roll 10 by wedge 24. ln the drawings,Figs, 1 and 3 the lever 34 is shown at the limit of its movement towardthe left with disk 3 locked immovably in the position shown through theengagement ot roll 36 with one oit our peripheral notches 38 with whichsaid disk is provided. Notches 38 are spaced lll) r with aperture 29 ofbracket 12, an-

f said disk apertures is directly between ram 32 and the upper end ofthe interior chamber 39 of a cage 40., said ram and cage being in axialalinement, another of 10 said apertures is at rest midway of its travelfrom ram 32 'to aperture 29, while the fourth aperture is at rest midwayof its travel from aperture 29 to ram 32.

During each revolution of gear ring 11 16 the roll 10 engages one of thefour slots 41 and moves disk 3 on its axis ninety degrees, but it willbe clear that if, after any step movement of said disk, the operatordoes not either swing arm 19 of bell-crank 20 19-20 toward the left,Figs. 1 and 9, to unset clutch 19-18a or swing lever 34 its fulldistance toward the righ-tito unlock the disk and raise ram 32, thenroll 10 will enarm and swing it toward the left, 25 Fig. 1. Thismovement of arm 25 by roll 10 acts through yoke 26, rock shaft 22, arm27, link 28 and arm 20, to unset clutch 411k-13FL and ltherebyautomatically stop ring 11. lllhen thus moved by roll 10 the 30 arm 25swivels on sleeve 25a which is held against turning;r by wedge 24.

Bed plate 7 supports a cylinder 42 containing a second ram 43 disposedin axial alinementwith the upper ram 32. Through a pipe 44 connectedtherewith oil or other fluid under pressure may be supplied to saidcylinder to raise the ram 43. Another pipe 43 equipped with anautomatically acting; relief valve 461 is connected with cylinder 42,said relief valve operating to cause the o il admitted to the cylindervia pipe 44 to yieldingly support the ram 43. That is. the relief valvepermits the ram 43 to yield downwardly when a predeter- 25 minedpressure is applied thereto in that .flirectiou, This ram is arranged sothat when at the limit of its downward movement its upper end is aboutflush with the top of base plate 7.

' mbe cage 40 is provided at its lower end with wheels or trucks 46 uponwhich it sts and may bc moved about. The interior rhaml'er 39 of thecake is of the same cross-sectional shape as the apertures 4, 4a,

etc.. disk 3 and is open at each end thereof except that a false bottom47 is arranged therein which is slidable lengthwise of Normally thisfalse bottom f the lower end of chamber 39 restinn' upon shoulders 48.

la placingu an empty caffe in position to be Afilled said cage is rolledonto bed plate 7 in position between rams 32 and 43 and with its upperend portion occupying a cage positioning socket 49 formed in table v 4,is in position immediately below and in 6. This socket 49 is shaped totit the noncirrular upper end port-ion 50 of the cage (Fig. 9), theengagement of said non-circular portion 50 with said socketpositioning,r the cage both angularly or rotatively and laterally sothat when it is properly placedwithin said socket its chamber 39registers exactly with each aperture of disk 3 while latter dwells, inposition, immediately above the cage.

When an empty cage is placed in position on bed plate 7 its false bottomis raised and supported by ram 43 with its top substantially flush withthe top of table 5 so that it forms the bottom of a mold cavity S0 whenthe first cake is forced into the lcage by ram 32 and thereaftersupports successively superposed cakes (which are forced down into thecage until the cage is full) as the cakes are forced from successivemoldingr apertures upon the previously transferred cakes. Theuppermostof these cakes after the initial cake constitutes the closureor bottom of a mold or die within which a cake is first compacted andfrom which it is thereafter transferred to the cage.

At right angles to the apertures or dies 4a and 4c and diametricallyopposite each other are the dies 4 and 4b. the former be- 95 ing emptyand havingr been stopped while traveling toward cooker 1 and the latterbeing iilled with meat and having been stopped while traveling1 towardthe cage filler made up of rams 32 and The die 100 or mold aperture 4occupies a position at which a plate and cloth may be placed therein toform the bottom of the cake while the die or mold aperture 4? occupies aposition at which the operator can place a cloth and plate on top of thecharge of meats contained therein to form the top of the cake.

yt is manifest that it is important that, the disk 3 be revolved with aikferiodic or 110 step-by-step movement to `rive a period of rest foreach die in its successive positions, namely, when thc bottom plate andcloth are inserted; when the, die is .filled with meats from the cooker;when the upper cloth and plate are placed on top of the meats in thedie, and when the meats iuclosed between the upper and lower plates andcloths are compacted and transferred to the cage.
